KEGIATAN TRANSPORTASI Mohem d Mun r pa s SubaMo den Fko Hidavarto Jurusan Flare Palatine IMPA University, glponegoro Semarang Terjadinya polusi edam oleh kegratan transporlasi berasal dad emisi gas CO, No,, VOC,, Pb den partkulat menimbulkan ganggiren terbadep kesehatan. Pb crape( masa< ke tuba manusia melaiui sampan solurar: pencernaan (digesti) atau melalui saluran pernafasan (inhilasi).

Karena Pb merupakan unsur toksis, mudah terakumulasi deism tubub manusia ()winger). tulang, (torah dan rambut) maka penentuan Konsentrasi Pb dalam tubuh manusia memedukan metodo angels yang sposilik. Metode analisis yang sering digunakan kntuk analtsis unsur kerlum.1 25 dalam rambut tanpa mempengaruhi komposisi kirma sampel adalah metode SpektrofotOmetri Serapan Atom 'ASS) yang berbasis pada pencacahan atom. Dan pengamatan kandungan Pb pada due dal) sampel rambut, dapat diperoleh hasilnya sebaga berikut : • Konsentrasi Pb =(4,334± R035 ) hg lg • Konsentrasi Pb = ( 0,837 ± 0,902) 9 Kandungan terseldul ookup linggi Seningge early penanganan maSalah pencernaran gas-gas buargan dari kegiaten trensportasi yang lebih serius.

SUMMARY NEUTRON ACTIVATION ANALYSIS TO DETERMINE THE ACCUMULATION OF Pb EMISION RATE FROM THE TRANSPORTATION ACTIVITY Mohammad Munir Aous Subavio clan Fko Fltdavanto Physics departement or matemafics and SaIns Faculy niPallea0/0 University Soninang The air pollution by transportation activity from transportation activity from vase emission of CO. Noy VOCa, Pb and the particulet are make the disturption of healthy. Pb can enter the body pass through the absorption of digestion duct or respiration duct. The hair can accumulate the Pb heavy metal as trace metal. Ph band at the bar is give information of Pb accumulation on the blood with Pb accumulation level at the hair which more great if it compare in other the body tissue. Because the Pb Is toxic element, it easy to accumulate in the body (tissue, bone, blood and heir), so to determine the Pb concentration in the body is necessary he specific analysis method. The analysis method which often be used to analysis the Pb trace element in the hair, without influence composition of sample chemrstry is the Atomic Absorption Spectrophotometri (AAS) that it is basis of the atomic chops. From the observation of Pb concentration at two hair sample, it the result is • The Pb concentration is ( 4,334 ± 0,035) Rg i g • The Pb concentration is = ( 0,837 t 0,002) (tg / g The concentration is high enough, so it needed the handling at gas pollution problems from the transportation activity with more seriously. The AAS method is precise to determine the element concentration on the trace concentration.
